Area walk= 24*6 ft^2
Area brick= (4/12)*(8/12) ft^2

2 answers
6' wide x 12 in/ft = 72 inches
72 inches/4 inches/brick = 18 bricks needed for the 6 foot side.
24' long x 12 in/ft = 288 inches.
288 inches/8 inches/brick = 36 bricks needed for the 24 foot side.
18 bricks wide x 36 bricks long = ?? bricks total to cover the area.
72 inches/4 inches/brick = 18 bricks needed for the 6 foot side.
24' long x 12 in/ft = 288 inches.
288 inches/8 inches/brick = 36 bricks needed for the 24 foot side.
18 bricks wide x 36 bricks long = ?? bricks total to cover the area.
